â€Å"For the most wild, yet most homely narrative which I am about to pen, I neither expect nor solicit belief. Mad indeed would I be to expect it . . . Yet, mad am I not – and very surely do I not dream. But tomorrow I die, and to-day I would unburthen my soul.† Thus the narrator begins to confess to murdering his wife in â€Å"The Black Cat†, just one of many fascinating creations from short story master and poet, Edgar Allan Poe. Edgar Allan Poe was born on January, 19, 1809 in Boston, where his mother had been employed as an actress. Elizabeth Arnold Poe died in Richmond on December 8, 1811, and Edgar was taken into the family of John Allan, a member of the firm of Ellis and Allan, tobacco-merchants. After attending schools in England and Richmond, young Poe registered at the University of Virginia on February 14, 1826, the second session of the University. He lived in Room 13, West Range. He became an active member of the Jefferson Literary Society, and passed his courses with good grades at the end of the session in December. Mr. Allan failed to give him enough money for necessary expenses, and Poe made debts of which his so-called father did not approve. When Mr. Allan refused to let him return to the University, a quarrel ensued, and Poe was driven from the Allan home without money. Mr. Allan probably sent him a little money later, and Poe went to Boston. There he published a little volume of poetry, Tam erlane and Other Poems. It is such a rare book now that a single copy has sold for $200,000.00 In Boston on May 26, 1827, Poe enlisted in The United States Army as a private using the name Edgar A. Perry. After two years of service, during which he was promoted to the rank of Sergeant-major, he secured, with Mr. Allan's aid, a discharge from the Army and went to Baltimore. He lived there with his aunt, Mrs. Maria Poe Clemm, on the small amounts of money sent by Mr. Allan until he received an appointment to the U.S. Military Academy at West Point. It was during his later years at West Point that he showed a remarkable talent for writing. Exploring themes as diverse as spirituality, astronomy, science and depravity, Poe’s writing is as powerful and arresting today as when he was first published.

Chemical Kinetics Lab Raport Paper

FE 106 GENERAL CHEMISTRY EXPERIMENT-3 CHEMICAL KINETICS PREPARED BY BURAK COBAN PURPOSE: In this experiment we will study the rate of decomposition of hydrogen peroxide to form oxygen according to the net equation: 2H2O2 (aq) 2H2O(l) + O2 by measuring the rate at which oxygen evolved, we will investigate how the rate changes with varying initial concentrations of hydrogen peroxide and iodide catalyst. After we will study the affect of changing its concentration the rate oxygen evolution.At the end of experiment we will summarize our results by attempting to write a rate law for the reaction, showing the defences on the concentrations of H2O2 and I. THEORY: Chemical reactions can be fast (think of any explosion ) or slow . It is very important to understand what is affecting the rate of the reaction and what is the mechanism of the reaction with such knowledge, we can often control a reaction to proceed at just the speed we need. we can thus avoid an explosion or speed up a reaction t hat seems too slow. In this chapter we start out by discussing rates of reactions and the rate law.The rate law indicates the affect that the concentration of the reactants has on the reaction rate. In general, adding more of a reactant speeds things up (rather like pushing the gas pedal to put more gas into the car engine ). But how much faster is the reaction if say the concentration of a reactant is doubled ? the rate law will help us answer such equations. Another way to affect the rate of a reaction is to change the temperature. We refrigerate food to slow the rate of bacterial metabolism that can cause food to spoil. If we want food to cook faster, we increase the heat.We also look at why some reactions seem to need a â€Å"kick start,† although once started, they continue to react. We will examine the activation barrier to reactions and its implications. Rate laws and kinetics experiments also tell us a lot about the mechanism by which a reaction occurs. Understanding the mechanism gives us another way to control the reaction. This knowledge enables us to design better catalyst or to create new compounds (such as new pharmaceuticals) that will be more effective. Differential Rate Laws: In many reactions, the rate of reactions changes as the reaction progresses.Initially the rate of reaction is relatively large, while at very long times the rate of reaction decreases to zero. In order to characterize the kinetic behaviour of a reaction, it is desirable to determine how the rate of reaction varies as the reaction progresses. A rate law is a mathematical equation that describes the progress of the reaction. There are two forms of a rate law for chemical kinetics: the differential rate law and the integrated rate law. The differential rate law relates the rate of the reaction to the concentrations of the various species in the system.Differential rate laws can take on many different forms, especially for complicated chemical reaction. However, most c hemical reactions obey one of three differential rate laws. Each rate law contains a constant, k, called rate constant. The units for the rate constant depend upon the rate law, because the rate always has units of mole L-1 sec-1 and the concentration always has units of mole L-1. Zero – Order Reaction: For a zero order reaction, the rate of reaction is a constant. When the limiting reactant is completely consumed, the reaction abrupt stops. Differential rate law: R=k The rate constant. k , has units of mole L-1 sec-1. First – Order Reaction: For first order reaction, the rate of reaction is directly proportional to the concentration of ane of the reactants. Differential rate law: R = k[A] The rate constant, k, has units of sec-1. Second – Order Reaction: For a second reaction, the rate of reaction is directly proportional to the square of the concentration of one of the reactants. Differential rate law : R = k [A]2 The rate constant, k, has units of L-1 sec-1. MATERIALS: ? Funnel, Florence flask, Beaker, Pipette ? Thermometer, ring stand, ? Distilled water 0,2M KI, H2O and H2O2 ? Burette, Rubber stopper, rubber tubes. PROCEDURE: Part A: ? 10 ml 0,2M KI and 15 ml distilled water was taken the flask. ? Flask was swirled until the solution comes to the bath temperature. ? After that 5 ml % 3 H2O2 was added quickly and stopper the flask. ? One of us swirled the flask in the bath, other one observed the change of the volume. ? Other one recorded the time when approximately 2 ml of the gas was evolved. Part B: ? Same experiment was done by using; 10 ml of KI + 10 ml of H2O + 10 ml of H2O2 Part C: ? Same experiment was done by using; 20 ml of KI + 5 ml of H2O + 5 ml of H2O2DISCUSSION: In this experiment, we discussed the rate of reactions. Reaction rate changed with kinds of reactant. For example in part A we put 10 ml KI and 15 ml distilled water an the other hand; in part B we put 10 ml KI ,10 ml H2O and 10 ml H2O2. After we determined. We saw that part A is slower than part B for this reason we can say rate is changed by nature of reactants. Another important effect is temperature. If temperature is high value reaction finish quickly. Maybe our results were effected temperature Because we put flask in heat water and rate of reaction is faster than low temperature. REFERENCES: GENERAL CHEMISTRY:PETRUCCI & HARWOOD = QUESTIONS = 1. Chemical kinetics is the study of the speeds, or rates, of the chemical reactions. A small number of factors control how fast a reaction will occur. Investigation of these factors provides clues to the ways in which reactants are transformed into products in chemical reactions. Some of the factors that influence the rate of a reaction are: ? Concentration; ? Pressure (particularly for reactions involving gases); ? Temperature; ? Surface area (for reactions involving solids); ? Catalyst; 2. The rate of reaction; R= 1/3*[d[A] / dt] = -1/2 *[d[B] / dt] =1/4* [d[C] / dt] = d[D] / dt . in this experi ment we will investigate concentration of substance according to the rate of reaction. The rate of reactions are effected temperature, pressure of gases, concentrations and volume when one of products appears or one of the reactant is wed up. 4. 50 ml 2 MA 20 ml water added 30 ml 4 MB Initial conc.

Philosophy of Love and Sex

Describe the three kinds of love: Eros, Philia and Agape Eros: †¢This is Greek term that refers to a type of love that is passionate, shows intense desire for something and is often referred to as sexual desires. Another word to describe this type of love is known as â€Å"Erotic. † As Plato writes: â€Å"he who loves the beautiful is called a lover because he partakes of it. † This quote explains that someone who admires the beauty of another is a lover because he shows the affection.The Platonic-Socratic explains that you can’t truly be friends with another after having sex with them. Philia: †¢Refers to the opposite sex and showing a tremendous amount of affection and appreciation towards friendship, parents, humanity. It should be a non-sexual relationship. Having friends is a good part of life. You need friendship to give you a notion to keep you happy to adjust to yourself. Forming a friendship is from liking each other, talking to one another or having the opposite of what you are (different).He also believes that friendship is based on pleasure but he also says that it’s not a real friendship then. Agape: †¢The love of humanity, belief in god and the combination of both Eros and Philia. You love everybody and everyone. Show affection towards your enemies and be nice to everyone. Love is unique and is distinguished by its nature and its character and how it is shown. It is also known as brotherly love.

College Students Still Getting Waisted essays

College Students Still Getting Waisted essays College Students Still Getting Wasted College students everywhere like to forget their studies every weekend and go out Amy with their friends. You would be surprised by how many of them are coming back early hours of the morning after consuming large quantities of alcohol. This is what they do for fun, but they dont know the harmful side effects that alcohol has. Some students use alcohol to signify that they are becoming adults, some use it to cope with stress brought on by teachers, peers, and family, and some use it just to simply have fun. No matter why it is being used it is still alcohol abuse. I am arguing that alcohol abuse should not be happening. I know that no matter where I am I will be around it but I would just like to make others aware of the harmful consequences that come from abusing alcohol. Hopefully after reading this a binge drinker and an alcoholic can be easily detected, prevented or helped. A binge drinker is someone who drinks five or more drinks in one sitting period, in other words this is the person standing next to the keg or refrigerator at parties, so he can have easy access to the alcohol when he finishes his drink. Most binge drinkers consider themselves to be light or moderate drinkers, though they notice they are usually drinking more than others. Members of fraternities and sororities report the most common cases of binge drinking among college students. High school students who are binge drinkers are more likely to apply to schools that have a reputation of being a party school as opposed to a school with the best educational background. Underage college students report that alcohol is easy to maintain and that they only drink for one reason, to get drunk. Even teachers can detect a binge drinker because they are the kids who are always missing class and when they do go they are late or unprepared.

The Top 6 Things You Should Never Sacrifice For Any Job

The Top 6 Things You Should Never Sacrifice For Any Job We all want that same astronomic rise to the top. But there are a few standards we should not be willing to compromise in the interests of success. Here are 6 examples of things not worth sacrificing on the altar of the corporate ladder. Your BackboneDon’t let yourself be abused, ridiculed, belittled, or harassed. There are plenty of systems in place to protect employees from these sorts of things. Show that you have a little backbone and some unflappable dignity and take advantage of them. At very least, you’ll be helping to ensure the next person doesn’t suffer similar maltreatment.Your SoulIt’s not all about the Benjamins. Success won’t be worth much if you’ve sold your soul to get it. Remember that your self worth is not tied to the size of your paycheck, or the fanciness of your car or your apartment. Not everyone can have a private jet. If you’re ever tempted to do something mercenary just to get paid, don’t. Take the high road instead. You can’t buy happiness. And once you spend your integrity, it’s very hard to build it back.Your Self-RespectIt’s important to fit in to your workplace culture, and to espouse the kinds of values your bosses emphasize. But doing something that feels wrong or abhorrent in any way to you just because you feel it’s what’s expected of you? That sucks. If you start to hate yourself for conforming to the questionable standards of others, then start looking for another job. Staying isn’t worth it.  Your IntegrityYour values are important. Shedding them out the window on your way to the top of the heap? Lame. Loyalty, honesty, empathy, graciousness†¦ these are important things that probably helped get you where you are. Protect them at all costs.If you have a hard time figuring this one out, make a list of the values most important to you and tack it up somewhere you will see it often. If you ever feel in danger of compromising any one of them, stop what you’re doing and re-strategize. When you still like yourself at 80, you’ll be glad you did.Your HealthIn the savage quest to succeed, it’s so easy to give up on all the so-called creature comforts like whole, healthy foods, nutrition, exercise, sleep, self-care. The list goes on. Take stock of your health and then do a thorough realigning of your habits. What good is success if you’re too exhausted, depleted, depressed to enjoy it? A work-life balance is important and will keep you fresher and sharper longer.Your PurposeYou’re so busy trying to get to the top of the next horizon that 5 or 10 years have gone by and you don’t remember why you went in this direction with such tenacity in the first place. Remember to have a bigger goal- your calling, if you will- and keep that goal in sight. Try and make every move somehow in service of this greater dream. Ask yourself where you want to be in 25 or 50 years, and make sure you’re taking steps, however incremental, to get there.

Best friends and archenemy Essay Example | Topics and Well Written Essays - 750 words

Best friends and archenemy - Essay Example The paper will analyze the relationship that exists between two contrasting extremes in our lives, our best friend and archenemy. Growing up each individual develops a keen interest in two people in his or her life, the best friend and the archenemy. The majority of people only relate relationships to the positive feelings we possess towards other individuals, however, in our subconscious mind we share our bond with our enemies. Some might even have a closer bond with their archenemy than their best friend. The archenemy has a vital role in each person’s life as he influences the decisions one makes and the way in which one behaves. The constant competition with the enemy is a driving factor for many individuals and yet they can spend their entire lives without realizing it. Best friends have a supportive role and play as a source of comfort and warmth for each individual. Enemies on the other hand bring out the competitive side of a person and push him or her to doing things they would be able to achieve without a stimulation factor. This shows the importance of an archenemy in a person’s life and how without this individual life would be very different and even worse than one might presume. Having the two in one’s life is like the day and the night. The essence and uses of the two times frames are different, we use the day to work, socialize with others and improve our social status. On the other hand, we use the night to sleep so we can have enough energy to vary out the activities that are essential in our lives. Such is the relationship between our best friend and archenemy. One provides us with the light and comfort meanwhile the other gives us the drive to excel in our lives. Without either of the two individuals, our lives and the measure of our success would be limited. A best friend picks us up when we are down, and is there to listen to us when nobody else will. He reassures us of our strengths and the good things that we have in our lives. The presence of our best friend makes us feel warm and comfortable even in the absence of words. A best friend is like a brother or sister and at times can be like a mother or a father. The archenemy is like an intruder, someone whose existence creates tension and increases your heart rate. In every situation he is always the target and the one to beat. He is like a catalyst in the reaction of life. There is no way one can truly achieve his full potential without being pushed or motivated. The archenemy also brings the joy and satisfaction that comes from a best friend. The victories one has over his rival can be even more welcomed than the good times he shares with his or her friend. As much as people might want to deny it, the archenemy is just as important as the best friend, and has an even larger role to play in some situations. Even in a movie there are two roles the good and the bad character. In the absence of a bad character, the hero is unable to shine or show his brilliance. He uses the negative attributes of the villain to capture the hearts of the audience and attain his heroic status. The characters need each other, just like each person needs both a best friend and an archenemy. The two are very different and yet so similar. They both make lasting impression in an individual’

American Imperialism (American History) Research Paper

American Imperialism (American History) - Research Paper Example It said that America was interested in the development of the countries in the western hemisphere and that any European country should not wield its imperialistic power in its domain. Though America was not as powerful as Great Britain or France in its powers at that time, it used the Monroe Doctrine to back its action of sending troops to Mexico against the French in 1866 and its acquiring of Alaska in 1867. One of the economic reasons for the foreign policy was to acquire more markets for American Industrial products. When one of American battleship exploded suddenly under the sea, US pointed its blaming fingers at Spain. The foreign policy made the US send troops to Cuba to fight against Spain domination of Cuba. William McKinley, the US president sent military troops to Cuba leading Spain and Us to declare war against each other. Eventually, Spain lost Puerto Rico and Guam to the US. Soon, America was contesting for the position of world power manifesting its power in the world scene. American journalist John used the term ‘Manifest Destiny’ in 1895, which was used to justify all actions of US in imperialism and expansion, acquisition of California and Alaska. As Michael Chimes says, that in the years that led to the Spanish American war, America saw the rise of ethnocentrism, manifest destiny, and Anglo-Saxonism. It was further fueled by nationalism. These gave the rationale behind America’s imperialism and foreign policy of the 18th and early 19th century. He discusses the philosophical underpinnings of the American Foreign Policy that led to Imperialism. He says: America’s rise to world power occurred in the fifty-year period between 1870-1920.   The Spanish-American War may be seen as the â€Å"point of no return,† the foreign policy event that conclusively committed us to imperial strength and a global presence.
